Description

The Radium Engineering GM LT4 LT5 PCV Valve Bypass (Part Number: rad20-0988) is designed to replace the OEM PCV valve installed directly into the engine valley of GM LT4 and LT5 engines. This bypass allows enthusiasts and mechanics to customize crankcase ventilation, diverting internal crankcase gases away from the supercharger housing where they typically deposit harmful residues. By replacing the factory valve, users gain flexibility in managing crankcase airflow to suit their specific performance or maintenance goals. The bypass is constructed to integrate seamlessly with the engine architecture, ensuring a secure fit and reliable operation. Installation instructions are available at RadiumAuto.com, making it straightforward for skilled technicians to upgrade or modify existing systems.

The Radium Engineering bypass not only enhances engine ventilation but also helps reduce unwanted crankcase deposits that can negatively impact supercharger performance and longevity. Its compact design minimizes space intrusion, maintaining the engine bay’s clean look while providing a functional upgrade. Made with durable materials, this bypass ensures long-lasting performance even under demanding driving conditions. Whether you are building a high-performance street vehicle or a track-ready machine, this component supports your goals by giving you control over crankcase gases.

Designed with ease of installation in mind, the Radium Engineering GM LT4 LT5 PCV Valve Bypass is suitable for experienced automotive enthusiasts and professional mechanics. It is not carburetor-approved and is intended solely for automotive applications where venting options are customized. This product does not come with provisions for external venting or oil catch can connections, making it ideal for users who wish to modify their crankcase ventilation system. Trust Radium Engineering’s reputation for quality and precision engineering to provide a reliable upgrade that supports your vehicle’s performance and maintenance needs.

Features:

  • Replaces OEM PCV valve installed in GM LT4 and LT5 engines
  • Allows customization of crankcase airflow and venting options
  • Constructed for durability and long-lasting performance
  • Designed for seamless integration with engine architecture
  • Installation instructions available for straightforward setup
